Question

1. How is sound produced? Name the form of energy required to start vibrations in a body producing sound

Answer 1

Answer:

The sound produced is transmitted through pressure waves within the object. An object vibrating back and forth rapidly pushes air forward to make way for itself. When a force is applied on an atom, it moves from its original position and exerts a force on the adjacent atom.

Answer 2

Explanation:

Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.

Body vibrates and it reaches us through the vibrations of the particle of surrounding medium.The sound requires a medium for propagation the medium of the body produce vibration in the particle of surrounding medium which travels in the form of wave with a certain speed depending upon the density.
